It seems no matter how hard you try, microwaves are difficult to keep clean. One mistake, one overheating of soup and the entire inside is caked in baked in tomato. Thankfully, according to tips site Cozi, you can heat a wet sponge or rag to steam the inside and clean it easily.

It ends up being a dual purpose solution, as we've already seen, heating a wet sponge is a good way to disinfect it, but once it's done, you can put it right to work cleaning out that dirty microwave. They recommend heating the sponge or rag for three to five minutes, then let it sit for a few more to let the steam loosen up the grime. After that, you should be able to wipe it clean. You might also consider combining it with the previously mentioned tip of heating a bowl of water with lemon in it to steam the microwave and add a nice scent at the same time.
